How to Handle asynchronous actions in Cypress?

Cypress is a JavaScript-based front-end testing tool that was made to address the blockers the QA team faces during web page testing. Cypress has various options to deal with asynchronous actions, as shown below:

  • Cypress has a comprehensive method to deal with asynchronous actions. Before continuing with your test, you might watch the results of your async function to make sure they occurred. It produces a command queue that runs sequentially and in the expected sequence.
  • For example, if User.createUserOnServer needs to wait for a successful API call, include the following code in your test to wait for the completion of the request: cy.server(), cy.route(), and cy.wait().
  • You can use third-party libraries such as cypress-promise; it will change how Cypress deals with async/await. With this library, you might be able to consider Cypress commands as promises that you can utilize "await" code in your "before" code.
  • AYou can use the code snippet given below to make sure that the async function get.s execute before the next Cypress command:
  • cy.wrap(null).then(() => myAsyncFunction());
  • You can put your async code in “cy.then()”. It is helpful when the test case has no completion point or multiple async actions are chaining together.
